Šafranko, Silvija; Živkovic, Pavo; Stankovic, Anamarija; Medvidovic-Kosanovic, Martina; Széchenyi, Aleksandar; Jokic, Stela – Journal of Chemical Education, 2019
This work combines laboratory quantitative analysis of colored solutions and common devices for digital imaging (digital or web cameras or mobile phones, i.e., smartphones). ColorX software, specially designed for this study, was used for data collection and analysis in order to calculate concentrations of colored solutions from measured RGB…

Meyer, Scott C. – Journal of Chemical Education, 2015
An upper-division undergraduate laboratory experiment is described that explores the structure/function relationship of protein domains, namely leucine zippers, through a molecular graphics computer program and physical models fabricated by 3D printing. By generating solvent accessible surfaces and color-coding hydrophobic, basic, and acidic amino…
